Sommarzan on "[Plugin: User Submitted Posts] BUG: no error alert when image is too big"

I have set image max width and height to 800 px.

When trying my form I choose a 1000x1000 px image.
After clicking "Submit" I don't see an error alert saying that the image is too big and my post hasn't been submitted - instead I get re-directed to my Redirect URL which just tells me the post has been successfully posted.
The URL of my Redirect URL is however http://www.company.com/submit-post/confirmation/?usp-error=width-max, but that is the only indication that something's gone wrong. And the common man won't see this, or understand it.

If I don't use a Redirect URL there is a small error alert, but this alert is not red-marked and the alert is placed above the form.

SUGGESTION: make the "Error: Image width exceeds maximum"-alert red-marked and place it next to the Upload image.

BUG: don't go to the Redirect URL if the max width is exceeded.

Thanks!
